DEVICE FOR CONVERTlNG MOTION.

SPECIFICATION forming part of Letters Patent No. 374,677, dated December 13, 887.

Application filed May 19, 1887. Serial No. 238,758. (No model.)

To all whom it may concern:

Be it known that I, GEORGE HEULLY, a citizen of the United States of America, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Devices for Converting Motion, of which the following is a specification, reference being bad therein to the accompanying drawings.

My invention relates to improvements which are especially designed for pressing cotton and other products, but which may be used generally as a motive power for driving machinery, which improvements will be fully understood from the following description, taken in connection with the annexed drawings, in which- Figure 1 is a side elevation of my improved machine. Fig. 2 is a diagrammatic end view of the same. Figs. 3 and 4 are sectional elevations of the stool and anti-friction roll's, between which a belt-pulley on the main reciprocating shaft rotates. Fig. 5 is a top view of one of the stools and its anti-friction roller. Fig. 6 is a vertical cross-section through Fig. 1, taken in the plane indicated by dotted line :0 x thereon.

Referring to the annexed drawings by letters, H designates the base of the motor, from one end of which rises cheeks H,which afford j ournal-bearings for a horizontal transverse crank-shaft, J. On one end of this shaft is keyed a large driving-wheel, I, and on the other endis keyed a drum, K, around which passes a belt, L, that passes around another drum on the driving or driven shaft. (Not shown in the drawings.) The crank 71. of shaft J transmits recilinear reciprocating motion to a crosshead, f,which slides in ways formed on the tops of the cheeks H, to which cross-head is suitably attached an endwise reciprocating shaft, B, which passes through vertical pillow-blocks k k, rising from and rigid with the base H. In practice I prefer to attach the rod B to the cross-headf by means of a well-known swivel, which will allow said rod to rotate at the same time it receives rectilinear reciprocating move ments. On this shaft is keyed a long cylinder, A, having a helical groove, a, extending from one end of it to the other. This grooved cylinder is journaled in a stationary pillow-,

block, M, provided with a stud, 19 which enters the helical groove a, on which stud may be an anti-friction collar. It will thus'be seen that when shaft B is moved it will be rotated in one direction by reason of the said stud p engaging with the cylinder A, and when said shaft B is moved backward it will be rotated in an opposite direction. Between the end of the helioally-grooved cylinder A and the pillow-block 7c,and beyond the pillow-block, the shaft B is prismatic or feathered, and on this part of the shaft is applied a pulley, 0, around which passes an endless belt, R, which is carried around an overhead pulley, D, applied on a shaft, F, journaled in hangers t 13. The pulley (l is prevented from receiving endwise motion by means of two horizontal anti-friction rollers, Q Q, the upper pointed ends of the spindles of which bear against the overhanging portions of two standards, N N, and the lower pointed ends of which have theirbean ing in blocks 1', which are vertically adjusta bly applied in recesses formed in brackets P, which are slotted at b, and vertically adjustable by loosening nuts on screw-bolts b, which bolts pass through slots in the vertical portions of the said stardards, as clearly shownin Figs. 4 and 5.

The standards N have broad bases provided with inverted-T-shaped ribs, which are received in a slot in the base H. The said bases are also slotted at d d, as shown in Fig. 5, through which slots pass vertically bolts 6 e, that rigidly'secure the standards to the base H. By these means the pulley C can be adjusted in true alignment with the overhead pulley D and prevented from receiving endwise movement. At the same time the antifriction rollers Q can be adjusted to compensate for wear.

On the overhead shaft F is also keyed a pulley, G, around which passes a belt, S, that is carried downwardand passed around a drum, S, keyed on a short shaft, 1;, (shown clearly in Fig. 2,) which shaft isjournaled in the pil-,

low-block 7c, and has keyed on it an arm, T, connected by a pitman-rod, V, to a similar arm, T, which is keyed on a short shaft, '0,

journaled in the pillow-block 7c, and having keyed on it a large wheel, E.

In operation the rotary motion is imparted to the crank-shaft J, which in turn transmits a rectilinear reciprocating motion to the shaft B through the medium of the cross-head f. By reason of the said shaft B being connected by a swivel to the said cross-head, and the engagement of the helical groove a in cylinder A with the fixed stud in the pillow-block M, the shaft B also receives rotary motion about its longitudinal axis. The square or prismatic portion of the shaft B transmits rotary motion to the pulley G,which, acting through the me dium of belts and pulleys, cranks, and a connecting-rod, transmits a rapid rotary motion to the belt-pulley E, and from this pulley power and motion may be derived for driving various machines.

Having described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. The within-described apparatus, consisting of the driving-wheel I and belt-Wheel K, keyed on acrank-shaft, J, a pitman transmitting rectilinear reciprocating motion to a cross-head, f, and a shaft, B, partly prismatic and mounted in suitable guides and attached to said cross-head by a swivel, a helicallygrooved cylinder, A, on said shaft adapted to pass through a pillow-block, M, having a stud, p, engaging with the groove in said cylinder, a pulley, 0, applied on the prismatic portion of said shaft B, means for preventing this pul ley from receiving endwise movement, the belt B, pulleys D and G, belt S, its pulley S',wheel E, arms keyed on the shafts of pulley S and wheel E, and the pitman-rod connecting said arms, all substantially as described.

2. The combination,with the endwise reciprocating and oscillating shaft B, the grooved cylinder A. and its stud p, and the belt-pulley 0, applied on the prismatic portion of said shaft, of the anti-friction rollers Q, adjustable, as described, and mounted in-longitudinal adjustable standards, for the purpose specified.

1 In testimony whereof I aflix my signature in presence of two witnesses.
